Characteristics and application of Baosteel's Cr-free ultrathick J coat for non-oriented silicon steel sheets

摘要

Baosteel's Cr-free ultrathick J coat for non-oriented silicon steel sheets has excellent insulation performance and has been successfully applied to middle and large scale electric power trains and wind electric power devices,which have stricter requirements than typical for coat insulation.In this paper,the characteristics and application of this type of coating for non-oriented silicon steel sheets were described in detail.
